No API key. No cost.</strong></p> <p>I built it because I got tired of seeing powerful AI tools locked behind paywalls and complex API setups.</p> <h2> Available Tools </h2> <div class="table-wrapper-paragraph"><table> <thead> <tr> <th>Tool</th> <th>What it does</th> </tr> </thead> <tbody> <tr> <td>⚡ <strong>Research Summarizer</strong> </td> <td>Paste any paper or article → get structured insights (core idea, key findings, implications)</td> </tr> <tr> <td>🧠 <strong>Code &amp; SQL Explainer</strong> </td> <td>Paste any code (C, Java, Python, SQL) → get line-by-line explanation</td> </tr> <tr> <td>🎓 <strong>MCQ Generator</strong> </td> <td>Paste any topic → get 5 high-quality multiple choice questions</td> </tr> <tr> <td>📄 <strong>Document Summarizer</strong> </td> <td>Upload PDF or Word → instant AI summary</td> </tr> <tr> <td>📋 <strong>Resume Analyzer</strong> </td> <td>Upload resume → get ATS score, weaknesses, and updated DOCX</td> </tr> <tr> <td>💻 <strong>Code Playground</strong> </td> <td>Write &amp; run Python, C, C++, Java, SQL, JavaScript with AI explanation</td> </tr> </tbody> </table></div> <h2> Why I built this </h2> <p>I'm an Assistant Professor of CSE in India and author of "Agentic AI Systems: Design &amp; Engineering". My students needed access to AI tools but couldn't afford expensive subscriptions or figure out complex API setups.</p> <p>So I built ZeroAPI – completely free, always.</p> <h2> Tech Stack </h2> <ul> <li>React + Vite</li> <li>Groq AI (Llama 3.3 70B)</li> <li>Deployed on Vercel</li> <li>SQLite in-browser for SQL playground</li> </ul> <h2> Try it </h2> <p>👉 <strong><a href="https://zeroapi.in" rel="noopener noreferrer">https://zeroapi.in</a></strong></p> <p>No signup.
